Flow direction
As shown in the symbols of table 2
P, A, B, X = 350 bar (for pilot pressure see also option /L9 at section 45
T = 250 bar for external drain (standard)
Operating pressure
T and Y with internal drain (option /D) = 120 bar DPHI; 210 bar DPHE (D)C); 160 bar DPHE (AC)
Ports Y and L (if required): 0 bar
Minimum pilot pressure for correct operation is 8 bar
